Read the original report. That's not the study's conclusion nor is it what the data indicate. And the study is a small study in a very homogeneous population of college students.

The OP pretty much never goes back to original reports or does any further investigation into the phenomenon comments on at all, but only ever relies on sensationalised and/or over-simplified media reports, which they post with clickbaity headlines and very little actual analysis. I really don't understand what the point is at all ... it's bizarre.

Between the shaky conclusions/reproducibility problems of the "soft sciences", and the clickbaity "did they even read the press release?" tendencies of the headlines on such things, I'm inclined to shrug off most such articles.

Though I'd imagine that, given that we're talking about relationships and attraction here, it's the *perception* of intelligence that's always more important than actual intellect.
